Thermal effects limit the gain, quality, and stability of high power fiber lasers and amplifiers.
In this paper, different values of heat conductive coefficients at the core, the first and second …

The present chapter looks at heat generation and heat removal in fiber lasers, particularly if
high–power or high–energy operation is required. In the context of the review, for the …

In this work we present a novel way to manipulate the effect of transverse mode instability by
inducing traveling waves in a high-power fiber system. What sets this technique apart is the …

High-power laser systems (HPLS) have wide-ranging applications in many prominent areas.
HPLS use laser diodes to pump fiber gain media. Understanding the functionality of both …

In the present paper, by increasing the radiation effect on convection heat term, the heat
transfer equation was rewritten at the fiber amplifier. By numerical solving of the fourth order …

In this paper, we present a study of thermal, average power scaling, change in index of
refraction and stress in photonic crystal fiber lasers with different pump schemes: forward …

The photonicscrystal fiberlasers and gas lasers make Yb3+ doped, hasbenn the subject of
theseveralresearches reported [1-6]. With the new type of the pump schemes with the high …

In this paper, we study the birefringence in photonic crystal fiber lasers PCFs and in
conventional fiber lasers in the bi-directional pump scheme in the linear cavity laser. We …
